About the Liberty
The Jeep Liberty first hit the markets in 2002 as a compact SUV. There have been two generations since its release, with the second generation debuting in 2008. The model was later discontinued by Jeep in 2012.
It has also been sold as the Jeep Cherokee outside of the North American market. The Jeep Liberty shares many similarities with its sibling, the Jeep Commander.
In terms of sizing, it sits between the smaller Jeep Wrangler and the full-size Jeep Grand Cherokee. Competition from outside of Jeep comes from the Toyota Hilux and Volvo XC60.
One of the most common issues that the Liberty, along with a number of Jeep models, has faced is P0456. This code indicates that there is a small leak coming from the EVAP system.
In most cases, this code is the result of a fuel cap that is not fastened properly. A defective cap that does not provide a proper seal can also be the culprit. However, it is possible that there is a faulty component in the EVAP system allowing a leak.
Fault code P0300 is a serious code that some Liberty owners have reported. This code indicates that there have been multiple random misfires.
Owners have reported that changing the ignition coil packs and spark plugs can be a simple solution to this issue. Other than that, there is a long list of potential causes for this issue. It is important to specify the engine type as some models like the 3.7 and 4.7 L V8s have some notorious faults.
Another issue that the model has suffered from is P0420. This code likely means that the catalytic converter in the first bank of the exhaust is failing.
Both a faulty catalytic converter and upstream exhaust leaks can typically be the cause of this problem.
